What is the pilot for the welding nut for ?

There is a pilot for positioning of the panel and nut. However, a large positional deviation does not occur even if there is no pilot because electrode incorporates an insulated positioning pin called a guide pin is currently used.
In terms of weldability, if there is a pilot, current will flow from the pilot to the panel, and variations in welding strength will increase due to the degree of shunt flow.
In addition, since the nut feeder requires delicate adjustment, selection errors due to improper adjustment are likely to occur.
For these reasons, we recommend that there be no pilot unless there is a special circumstance.
